BUNDLE-CARRIER FOR SELF-BINDING HARVESTERS.

SPECIFICATION forming part of Letters Patent No. 721,351, dated February24, 1903.

I Application filed June 3, 1899. Serial No. 719,224. (No model.)

To aZZ whom it may concern:

Be it known that 1, JOHN F. APPLEBY, of Chicago, in the county of Cookand State of Illinois,have invented certain new and useful ings on atine-bar and provided with crank ends journaledin a tine-shiftingbar,with connections extending therefrom to the drivers platform,whereby the bar may be shifted and the tines rocked to cause theirpoints to trend backward and downward to discharge the Heretoforecarriers of this class have been so arranged that the driver in order todischarge the bundles must exert sufficient force upon the 'foot-treadleto practidles and their resistance to discharge as the fingers or tinesare folded beneath them. This necessitatesconsiderable effort upon thepart of the driver, and the operation being repeated throughout the dayinvolves an amount of labor which is exhausting, while the work itselfis not as smoothly and satisfactorily performed as desired.

It is the object of my invention to improve this class ofbundle-carriers, so as to make the dumping or discharge of the bundlespractically automatic, the operator being required to do nothingmorethan to lift his foot from the foot-treadle, the weight of the footserving as 'a brake on the tripping mechanismand the weight of thebundles being utilized to shift the mechanism and fold the tines, so asto discharge thebundles, the

tines being restored to their normal position by a spring.

dumping position. Fig. 2 is a plan view of the same parts, showing thebundle-carrier in the normal position-thatis, with the tines extended orin the carrying position-and Fig.2 is a similar view showing the, tinesfolded or in the dumping position. Fig. 3 is a detail view showing thefoot-treadle and its operating-lever in side elevation. Fig. 4 is adetailed view of a triangular frame forming a support for a bell-cranklever which operatesthe shifting mechanism. Fig. 5 is adetail of anadjustment-plate for changing the set of the tilting. or dumpingmechanism.

Thebundle-carrierinthe constructionillustrated is hinged to andsupported from a pipe or bar 6, on which the binding mechanism slides,by means of the straps 7, which are provided with hooks at one end totake over the bar 6, their opposite ends being rigidly secured to thetine-bar 8. w The tines 9, as shown, are iron rods having straightportions 10, which pass through bearing-boxes 11, secured to the underside of the tine-bar, and crank ends 12, which are journaled in theshifting-bar 13. A triangular support 14 has .studs15, which arejournaled in sockets 16 on two of the boxes 11, located near the middleof the tine-bar, the apex of the triangular support projecting towardthe machine between two of the crank ends of the tine-bar and having anupstanding stud 17 to form a vertical pivot for a bell-crank 18. Thisbellcrank is connected by a brace 19 to the machine-frame, the bracebeing hinged to the frame and having an upturned end 20, forming avertical pivot passing through a long bearing on the bell-crank. Thishearing or pivot, as well as the bearing for the upstanding stud on thetriangular support, are long, so as to prevent any tilting or tippingmovement in the connection, while permitting the parts to swing or turnfreely around their pivotal axes. To the opposite arm of the bellcrankare pivotally connected two rods 21 22, the rod 21 being secured atitsopposite end to an adj usting-plate 23, clamped on the shifting-bar13, and the rod 22 being sleeved over a crank 24 on the rock-shaft 25,the latter be-' ing supported near its ends from the framework of themachine. At its opposite end the rock-shaft has a crank 24 anda bar 26is pivotally secured thereto and to a foot-treadle 27, which is pivotedon the seat-bar support 28. The connecting-bar 26 is preferably formedin two parts adjustably connected together, so as to provide foraccurate adjustment. This connecting-bar has a retractingspring 30hitched thereto and also to the seatbar support.

The parts connected as above described are intended to operate in thefollowing manner: In the normal position the tines extend outwardly inline with the platform, and they are usually curved upwardly, so as tohold a number of bundles of grain. They are sustained in this positionnormally by the pull of the retracting-spring 30. The driver rests onefoot upon the treadle 27, and the weight of the foot is sufficient whenassisted by the spring to hold the tines extended under the weight ofany number of bundles which it may be desired to collect at one time. Inthis position the pivotal points of the brace 19 and bell-crank arenearly in line, the pivot 20 being slightly out of line to preventabsolute locking of the bell-crank. The positions of the pivotal pointsof the bell-crank and brace determine the force necessary to hold thetines extended under the weight of the bundles. Preferably they are sodis posed that, as above stated, the weight of the drivers foot inaddition to the pull of the spring will hold the tines extended undertheir superimposed load of bundles. To dump the bundles, it is onlynecessary for the driver to lift his foot, when the weight of thebundles upon the tines will overcome the pull of the spring sufiicientlyto cause the tines to fold. In this folding operation the bundle-carrier swings down slightly upon its pivotal support from theframework of the machine, the two positions being shown best in the fulland dotted lines, respectively, of Fig. 1. The pivotal points of thebrace and the bell-crank also change their relations during this foldingaction, the secondary position being shown in Fig. 2 In passing from oneposition to the other the leverage afforded by the weight of the bundlesis greatly accelerated toward the close of the movement. As soon as theoperator lifts his foot and the tines commence to fold under the weightof the bundles the pivotal points of the brace and the bell-crank changetheir relation, so that the power exerted by the bundles tending to foldthe tines is greatly increased and is greater than could be opposed bythe operator through the foot-treadle. This makes the delivery not onlyrapid, but certain and elfective. The shortening of the line between thecenter of the bell-crank and the connecting-point of the brace to theframe, due to shifting of the pivotal points of the bell-crank and thebrace, also permits the downward swing of the bundle-carrier as a whole,and by this means the tines are brought to a slant, which facilitatesthe discharge of the bundles, the slope of the tines being such as topermit the bundles to slide off readily. Normally I support thebundle-carrier at a slightly higher elevation than heretofore in orderto render more elfective the weight of the bundles upon the tines toassist in the dumping operation, while in the folded position the tinesare brought practically into contact with the ground and in the mosteifective position for dumping. The sides of the triangular supportafford stops to limit the movement of the tines in both directions. Inthe normal position the arm of one tine strikes upon one of the sides ofthe triangular support, while in the dumping position the arm of theother tine strikes upon the opposite side of the triangular support.

Obviously the principle of my invention may be embodied in structuresconsiderably varied from that herein illustrated and described; but thisprinciple of employing the weight of the bundles to effect the dumpingis the essential feature of my invention.

I am aware that bu ndle-carriers have heretofore been used in whichfolding tines connected to a tine-shifting bar are employed, and I amalso aware of the prior use of bundle-carriers in which the carrier ishinged to the frame of the machine and held in position to receive thebundles by a locking mechanism which when released permits thebundle-carrier to drop down under the weight of the bundle, the tinesturning upon their journals and folding or collapsing as they arewithdrawn from beneath the bundles by the movement of the machineforward. In the last-named construction the carrier has to be returnedto its normal position by means of power applied to a foot lever ortreadle by the driver; but in my construction the weight of the bundlesis made to operate upon a hinged carrier and through the instrumentalityof a second connection to the framework the folding is accomplishedentirely by the weight of the bundles. Before the tines strike theground the movement carries the bundles rearward, thus freeing the tinesfrom the bundles before another bundle is discharged from the bindingmechanism, while the normal position of the bundle-carrier is recoveredby the aid of the retracting-spring, which acts promptly and without anyeffort upon the part of the operator.

I claim 1. In a bundle-carrier of the type described the combinationwith a tine-supporting bar hinged to the framework of the machine and asupport carried thereby, of a tine shifting or folding bar and a jointedconnection between the tine shifting or folding bar and the framework,said connection comprising a member pivoted upon said support, linkspivotally connecting said member to the tineshifting bar and to saidframework respectively, and means under the control of the driver forrocking the pivoted member, substantially as described.
